## javax.jms
Interface QueueConnection

All Superinterfaces:
  Connection

All Known Subinterfaces:
  XAQueueConnection

public interface QueueConnection
extends Connection

A `QueueConnection` object is an active connection to a point-to-point JMS provider. A client uses a `QueueConnection` object to create one or more `QueueSession` objects for producing and consuming messages.

A `QueueConnection` can be used to create a `QueueSession`, from which specialized queue-related objects can be created. A more general, and recommended, approach is to use the `Connection` object.

The `QueueConnection` object should be used to support existing code that has already used it.

A `QueueConnection` cannot be used to create objects specific to the publish/subscribe domain. The `createDurableConnectionConsumer` method inherits from `Connection`, but must throw an `IllegalStateException` if used from `QueueConnection`.

Method Summary
`ConnectionConsumer` | `createConnectionConsumer(Queue queue, String messageSelector, ServerSessionPool sessionPool, int maxMessages)` Creates a connection consumer for this connection (optional operation).
`QueueSession` | `createQueueSession(boolean transacted, int acknowledgeMode)` Creates a `QueueSession` object.

Method Detail

### createQueueSession

    public QueueSession createQueueSession(boolean transacted,
                                           int acknowledgeMode)
                                    throws JMSException

  Creates a `QueueSession` object.

  Parameters:
    `transacted` - indicates whether the session is transacted
    `acknowledgeMode` - indicates whether the consumer or the client will acknowledge any messages it receives; ignored if the session is transacted. Legal values are `Session.AUTO_ACKNOWLEDGE`, `Session.CLIENT_ACKNOWLEDGE`, and `Session.DUPS_OK_ACKNOWLEDGE`.
  Returns:
    a newly created queue session
  Throws:
    `JMSException` - if the `QueueConnection` object fails to create a session due to some internal error or lack of support for the specific transaction and acknowledgement mode.
  See Also:
    `Session.AUTO_ACKNOWLEDGE`, `Session.CLIENT_ACKNOWLEDGE`, `Session.DUPS_OK_ACKNOWLEDGE`

### createConnectionConsumer

    public ConnectionConsumer createConnectionConsumer(Queue queue,
                                                       String messageSelector,
                                                       ServerSessionPool sessionPool,
                                                       int maxMessages)
                                                throws JMSException

  Creates a connection consumer for this connection (optional operation). This is an expert facility not used by regular JMS clients.

  Parameters:
    `queue` - the queue to access
    `messageSelector` - only messages with properties matching the message selector expression are delivered. A value of null or an empty string indicates that there is no message selector for the message consumer.
    `sessionPool` - the server session pool to associate with this connection consumer
    `maxMessages` - the maximum number of messages that can be assigned to a server session at one time
  Returns:
    the connection consumer
  Throws:
    `JMSException` - if the `QueueConnection` object fails to create a connection consumer due to some internal error or invalid arguments for `sessionPool` and `messageSelector`.
    `InvalidDestinationException` - if an invalid queue is specified.
    `InvalidSelectorException` - if the message selector is invalid.

    `ConnectionConsumer`
